New extension GRP flat roof - Cold or Warm construction?

Postby adjsanders » Wed Sep 16, 2020 4:25 pm

Hi All

We are currently having an extension built. The roof is going to be a flat roof with GRP covering, but there's some confusion about whether the structure of the roof is going to be a cold structure or a warm structure with regards to the insulation.

Can anyone shed some light on which is best with a GRP covering? Is one option more common than the other?

And, what are the pros and cons of a warm roof vs a cold roof in the context of GRP?

Hi adjsanders
Suggest you look at grp roofs on this web site. Personally I would go for a cold roof construction.
